microsoft office license question
I have a copy of microsoft office 2007, which I installed on to my desktop PC and laptop, but then I restored my laptop to factory settings and installed it again, so I have installed it 3 times. I recently bought another laptop, and want to install office 2007 on it too. I'm just confused on what it says on the back of the office 2007 box, "licensed for 3 PC's". Does this mean that I can install it onto 3 different pc's as many times as I want, or I can only install the software 3 times (I have already; once on my desktop PC and twice on my first laptop).
Thanks for your help.
